I fell over a year ago and the area directly after my knee remained with a now noticeable lump on each of my legs, in the exact same spot.I do not have diabetes,high blood pressure or any health issues currently. The swelling does reduce when i took water pills,prescribed after the doctor saw the swelling ,He said it was nothing and could be from veins, they are also permanently showing since I the fall..I am 30 years old. I currently lost 19 lbs but it hasn't helped. I walk every morning and use my treadmill in between . Can you kindly give me some advice as to what the problem may be.
